Shrub rose plant named ‘KORumneza’

ABSTRACT

A new and distinct variety of rose with long lasting, novel pastel pink flowers, and attractive foliage with excellent disease resistance. It exhibits upright to bushy growth with abundant flowers. The new variety propagates well from cuttings and by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Latin name of genus and species: The botanical classification of the newrose plant is Rosa hybrida.

Variety denomination: The denomination of the new variety is‘KORumneza’.

CROSS REFERENCES AND FEDERAL R&D STATEMENT

There are no cross referenced or related applications. This variety wasdeveloped without the aid of any research grant.

BACKGROUND OF THE INVENTION

The new variety of rose plant of the present invention originated from acontrolled crossing in a breeding program of two distinct parents duringthe summer of 2002. The crossing was between an un-named seedling, theseed parent, and another un-named seedling, the pollen parent by thesame inventor.

The resulting seeds were planted during the following winter. Theresulting seedlings were evaluated and exhibited distinctive physicaland biological characteristics. The new rose plant was selected as asingle plant from the seedling beds due to its superior characteristicsand asexually propagated for further evaluation. This new anddistinctive rose variety is named ‘KORumneza’.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from its seed parent, anun-named seedling, by the following combination of characteristics:

-   -   1. ‘KORumneza’ has pastel pink flowers, whereas the un-named        seedling has deep pink flowers.    -   2. ‘KORumneza’ has an upright to bushy growth habit, whereas the        un-named seedling has a spreading growth habit.

The new rose plant may be distinguished from its pollen parent, anun-named seedling, by the following combination of characteristics:

-   -   1. ‘KORumneza’ has a semi-double petal count, whereas the        un-named seedling has a double petal count.    -   2. ‘KORumneza’ has excellent disease resistance, whereas the        un-named seedling has average disease resistance.

The objective of the hybridization was to create a new and distinct roseplant with unique qualities, such as:

-   -   1. Uniform growth and flowering;    -   2. Abundant attractive, recurrent flowers;    -   3. Attractive and abundant foliage; and    -   4. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose cultivarsknown to the inventor. These objectives have been substantially achievedand in that distinguish ‘KORumneza’ from all other varieties of which Iam aware.

As part of a rose development program, Tim-Hermann Kordes germinatedseeds from the aforementioned hybridization and conducted evaluationsand observations on the resulting seedlings in a controlled environmentin Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibiteddistinctive physical and biological characteristics. The new rose plant‘KORumneza’ was selected in May 2003 from the seedling beds to beasexually propagated for further evaluation. The first asexualpropagation of ‘KORumneza’ was done by budding in July 2003 at theinventor's nursery in Offenseth-Sparrieshoop, Germany.

These initial and other subsequent propagations conducted in controlledenvironments demonstrate that ‘KORumneza’ reproduces true to type insuccessive generations of asexual reproduction.
